-
-   Please note that Roaming support is not available on Windows Phone 8.0,
-   due to limitations in the OS itself.  Attempts to use it will fail, with
-   SDL_GetPrefPath() returning NULL (if SDL_HINT_WINRT_PREF_PATH_ROOT is
-   set to "roaming" on that platform).  Windows Phone 8.1 does not have this
-   limitation, and does support Roaming data.

- *   * "roaming" - Use the app's 'roaming' folder to store data.
- *                 On Windows Phone 8.0, this setting is not supported due to

- *   * "old"     - Use the app's 'local' folder on Windows Phone, and 'roaming'
- *                 on non-Phone versions of WinRT.  This mimics behavior found
- *                 in SDL 2.0.3's implementation of SDL_GetPrefPath() for WinRT
- *                 (and was changed for SDL 2.0.4, further details of which are
- *                 in the "Caveats" section of SDL's
- *                 [WinRT README file](README-winrt.md).
- *
- *  The default is to use the app's "local" folder.
- *
- *  Details on 'local' verses 'roaming' folders can be found on MSDN, in
- *  the documentation for WinRT's Windows.Storage.ApplicationData class,
- *  (available at http://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.applicationdata ).
